SPECIFICATION forming part of Letters Patent No. 473,757, dated April 26, 1892.

Application iiled May 11, 1891. Serial No. 392,336. (No model.)

T0 all whom t may concern:

Be it known that I, JOHN KANE, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, haveinvented certain Improvements in Vindow-Sash Tighteners, of which the following is a specification.

The object of my invention is to provide simple and efficient means for firmlytightening and preventing the rattling of a windowsash when the same is either closed or open and at the same time to permit 0f the ready release of the sash when it is desired to raise or lower it. This object- I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l represents a perspective view of part of the window frame and sash of a railway-car, illustrating the application of my improved sash-tightening device thereto. Fig. 2 is an enlarged side view, partly in section, of part of the sash and its retainer. Figs. 3 and 4. are sectional plan views of part 0f the sash and frame with the tightener, Fig. 3 showing the latter in position for holding the sash, and Fig. Lt showing the tightener retracted, so as to permit free movement of the sash; and Fig. 5 is a sectional plan view illustrating the use of a lockingor supporting bolt in combination with the tightener.

A represents part of the window-frame, having suitable guide-strips d a', between which the sash B can slide vertically in opening and closing, these guide-strips, however, being such that they do not closely confine or embrace the side rails of the sash, one of the guide-strips d being, by preference, beveled, as shown in Fig. l and more fully in Figs. 3 and 4..

On each of the side rails of the sash is a beveled bar D, which may extend throughout the entire length of the sash or throughout only a portion of such length, or which may be in sections, if desired. The bar D is adapted to engage withthe beveled guidestrip a of the window-frame, so as to tighten the sash in its guides, as shown in Fig. 3; but the bar can be withdrawn, as shown in Fig. 4., so as to loosen the sash and permit of the ready raising orlowering of the same. Each bar D is carried by a pair of bolts h, guided in casings F on the side rail of the sash, one

acted upon by a spring z', tending to depress it, and thus actuate the levers G, so as to project the bolts h and move the tightening-bars D outward or into operative position, as shown` 6"\5 f in Fig. 3. The lower lever G projects laterally beyond the casing, so that it can be conveniently manipulated, a laterally-projecting lug lc on the lower casing forming a rest for the thumb or finger in operating the lever G.

On the outside of one of the lower casings F is a bolt J, connected by a Web m, Fig. 5, to the bolt b in said lower casing, so as to move therewith, this outer bolt J being adapted to engage with the usual stops J on the window-frame, so as to hold the window in different positions and prevent the closing of the same by the shaking or jarring movement of the car. In ordinary cases, however, the action of the beveled bars D upon the sash will be sufficient to holdy the sash in any desired position of adjustment, the bearingsurfaces of the guide-strips ahbe-ing of uniform character from top to bottom of said strips, so that the tightening-bars will properly engage with said bearing-surfaces in Whatever position the sash may be.

Although it is preferable to bevel both the guide-strip a of the window-frame and the tightening-bar D of the sash, but one of these may be beveled, if desired. For instance the strip a may be shaped as shown by dotted lines in Fig. Lt or the beveled strip may be used in connection with a rectangular bar on the sash.

Having thus described myinvention, I claim and desire to secure by Letters Patentl. The combination of the frame having guide-strips, the sash, the tightening-bar mounted on the sash and engaging with one of the guide-strips of the frame, and means for advancing and retracting said bar, one of IOO the engaging parts being beveled, and the bearing-surface of the guide-strip being uniform from top to bottom, substantially as specified.

2. The combination of the frame having guide-strips, the sash, the tightening-bar engaging With one of the guide-strips, one or other of said parts being beveled, retracting devices engaging with the upper and lower portions of said tightening-bar, and a bar for connecting said retracting devices, substansaid levers, and a spring acting on said bar, substantially as specied. y

4f. The combination of the Window-frame having guide-strips, the sash, the tighteningbar mounted on the sash and engaging with one of the guide-strips, one or other of said parts being beveled, a locking-bolt adapted to engage with stops on the Window-frame, and -means for simultaneously advancing and retracting the tightening-bar and the lookin gbolt, substantially as specified.

In testimony whereof I have signed my name to this specication in the presence of tWo subscribing Witnesses.

JOHN KANE.
